I apologize, but there seems to be a mistake in the question. The coordinates provided for the Port Bienville Boat Launch are actually located in Mississippi, not Wisconsin.

According to the Mississippi Department of Wildlife, Fisheries, and Parks, the Port Bienville Boat Launch is a concrete boat ramp with two lanes and a courtesy dock. It is approximately 35 feet wide and can accommodate various sizes of boats.

This boat ramp services the Bay of St. Louis, which is a part of the Gulf of Mexico. It is located near the Port Bienville Industrial Park in Hancock County, Mississippi.

Various types of watercraft are permitted on the Bay of St. Louis, including power boats, sailboats, kayaks, and canoes. However, there may be certain restrictions or regulations in place, such as speed limits or designated areas for certain activities. It is important to check with local authorities for the latest information and guidelines.
